Kimi Raikkonen will return to Ferrari in 2014 to drive alongside Fernando Alonso.
The announcement came just hours after Felipe Massa announced on Twitter he was leaving the team.
Raikkonen’s move to the team had looked inevitable after Daniel Ricciardo was announced as the second Red Bull driver prior to the Italian Grand Prix.
The Finn previously drove for Ferrari from 2007- 2009.
On making his return to F1 in 2012 he drove for Lotus.
